MANURE-LOADER.

Specification of Letters Patent.

Patented May 3, 1910.

Application filed September 29, 1909. Serial No. 520,110.

To all whom t mm] concern:

Be it known that I, JOHN NoLD, a citizen of the United States, residinovat Tolstoy, in the county of Potter and State of South Dakota, haveinvented new and useful Improvements in Manure-Loaders, of which thefollowing is a specification.

This invention relates to hoisting and loading apparatus of that classwhich is employed for the purpose of elevating manure, dirt, gravel andother like material for the purpose of dumping or loading the same ontoa manure spreader, wagon box or other receptacle, and it has partlcularreference to that class of loaders which comprise a frame and a dumpingplatform together with elevating mechanism for such platform; the latterbeing adapted to be lowered to a position in which the material to beloaded may be deposited thereupon by means of scrapers of ordinaryconstruction after which such platform may be elevated to dumpingposition.

The present invention has for its object to simplify and improve theconstruction and operation of this class of devices and with these andother ends in view which will readily appear as the nature of theinvention is better understood the same consists in the improvedconstruction and novel arrangement `and combination of parts which willbe hereinafter fully descsribed and particularly pointed out in theclaims.

In the accompanying drawings has been illustrated a simple andpreferredl form of the invention; it being however understood that nolimitation is necessarily made to the precise structural details thereinexhibited, but that changes, alterations and modifications within thescope of the invention, may be resorted to when desired.

In the drawings: Figure 1 is a perspective l view of a loading apparatusconstructed in accordance with the invention. Fig. 2 is a verticaltransverse sectional view of the same. Fig. 3 is a perspective viewshowing one of the latches for securing the leaves of the dumpinglatform. Fig. 4 is a perspective view ofp one of the hinges upon whichthe leaves of the dumping platform are supported.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The frame of the improved loading apparatus compises a bottom frame Aand a top frame each of rectangular shape; the

top frame being supported by corner posts 5 being preferably constructedof angle irons. Side posts or uprights 6 rise from the side sills 7 ofthe bottom frame to a point above the top frame, said u rights beingconnected with side sills ofthe ottom frame by means of inclined braces8 whereby they are strongly reinforced.

The uprights (3 are provided adjacent to their upper ends with bearingsfor a shaft 9 constituting a winding drum and which is provided adjacentto one end with a grooved wheel or pulley 10 and with a brake wheel 11engaged by a flexible brake 12 one end of which is secured to a bracket13 and the outer end of which is connected by a link 1.4L with a brakelever 15 pivoted upon one of the uprights G and adapted to engage aratchet bar 16 upon one of the braces 8 whereby said lever may besecured in position to hold the flexible brake strap in engagement withthe periphery of the brake wheel under varying degrees of tension.

The dumping platform of the machine is composed of end members 17adapted, when the patform is lowered, to lie adjacent to the inner facesof the end sills 18 of the bottom frame A; the end bars or end members17 are connected by longitudinal bars 19 upon which the leaves 2O of thedumping platform are pivotally supported by means of hinged members Ceach composed of two oppositely disposed plates 21 having ears or lugsv22 connected by means of pivots 23. The plates 21 of the hinge membersare bolted or otherwise secured respectively upon the undersides of theleaves 20 and upon the upper sides or faces of the bars 19, oneor morehinges being utilized to secure each of the leaves in position. Suitablysupported pivoted catches 24 are provided to engage the outer edges ofthe platform leaves 20 for the purpose of normally sustaining saidleaves 1n approximately horizontal position. Said catches are providedwith actuating springs 25 and with beveled end portions 26 which arenormally engaged by rollers 27 supported for rotation in yokes 28 whichare supported for oscillation in bearings 29 upon the platform leaves,it being understood that the tension of the springs 25 in connectionwith the friction between the parts will be sufficient to hold thecatches in engagement with the platform leaves against the gravity ofthe rollers, which are normally supported upon the beveled ends of thecatches. Suitably secured upon the uprights 6 adjacent to the top frameB are brackets or arms 30 which are reinforced by suitably arrangedbraces 31 and which serve, when the dumping platform is elevated, toengage` and to depress the rollers27, thereby actuating the catches 24against the tension of the springs 25, disengaging the catches from theplatform leaves and permitting the latter to dump as indicated by dottedlines in Fig. 2.

Flexible hoisting elements such as cords or cables 32 are connected withthe dumping platform adjacent to the four corners of the latter, saidhoisting elements being guided over suitably disposed guide members suchas pulleys 33 to the shaft 9 upon which they are suitably wound. Ahoisting rope 34 is attached to the periphery of the hoisting wheel l0upon which it is wound after which it is guided over a pulley 35 tothepoint where the draft is to be applied. The hoisting mechanism ispreferably operated by animal power, but it is obvious that a mechanicalmotor of suitable construction may be used when preferred.

In the operation of this device, suitable approachers consisting ofinclined planes, are provided adjacent to the ends of the bottom framefor the purpose of facilitating the admission of scrapers to the dumpingplatform when the latter is in a lowered position. When a sufficientload has been deposited upon the platform, where the load is naturallybacked above the meeting edges of the leaves, power is applied to thehoist'- ing rope thereby unwinding the said rope from the wheel 10, androtating the shaft v so as to Wind the flexible elements 32 upon thelatter, and thereby elevating the platfform with its load. When theplatform reaches the desired elevation, the rollers 27 will be engagedby the brackets 30 and will thereby be actuated to disengage the catches24 from the leaves 20, but as the catches 24 become thus disengaged, therollers 27 will engage the upper faces of the leaves adjacent to theouter edges of the latter, being held in engagement by the brackets 30and thus temporarily preventing the tilting of the leaves 20 under theimpulse of the load. The motive power is at this point stopped and thebrakey is setl to temporarily retain the parts in position while theload receiving vehicle is driven under the platform. The pressure of thebrake may now be released, thus causing the platform leaves to be tiltedunder the gravity of the load, the latter being discharged into thereceiving vehicle. The dumping may be performed quickly if desired, butany unnecessary shock may be avoided by gradually releasing the tensionof the brake thus causing the leaves 20 to be tilted gradually while theplatform is being lowered sufficiently to disengage the rollers 27 fromthe brackets 30, such disengagement being effected by `the beveled endsof the catch members 24 under the tension of the springs 25. Byresetting the brake the descent of the platform is now temporarilystopped until the vehicle has been driven out of position from under theplatform after which the latter may be lowered into position for thereception of another load.

Having thus described theY invention, what isv claimed is l. In a deviceof thev character described, a frame, a dumping platform having tiltingleaves, spring-actuated latch members engaging the leaves adjacent totheir outer edges to support them normallyV in approximately horizontalposition, hoisting means for the platform, means for disengaging thelatches when the platform reaches a predetermined elevation, and meansfor retaining the releasing means in engagement with the tilting leavesuntil the platform begins to descend, thereby preventing the leaves fromtilting until the descent has commenced.

2. In a device of the character described, a dumping platform havingtilting leaves, hoisting means for said platform, brake meansforchecking thev descent of the platform, catches engaging t-he tiltingleaves to support the latter normally in approximately horizontalposition,y catch releasing means consisting of movably supportingrollers adapted to engagevthe leaves, and roller engaging bracketssupported to hold the rollers temporarily in engagement with the leaves.

3. In a device of the character described, a dumping platform havingtilting leaves, hoisting means for said platform, brake means to supportthe platform at various elevations', and to check the descent thereof,spring-actuated catches supported adjacent to the outer edges of theplatform leaves to sustain said leavesnormally in horizontal position,yokes Asupported pivotally upon the l leaves adjacent to their outeredges, rollers carried by said yokes and adapted to actuate the catchesto disengage the latter from the leaves, and suitably supported bracketsadapted to eng'age the rollers to actuate the catches and to temporarilyhold said rollers in engagement with the leaves to keep the latter fromtilting.

In testimony whereof I affix my signature in presence of two witnesses.
